The SNW-8138630818-12-I1 from Sage Millimeter is a waveguide junction isolator that operates from 81 to 86 GHz. Compared with a Faraday isolator, the waveguide junction isolator offers an insertion loss of 0.8 dB and a much shorter insertion length for system integration. However, it a nominal isolation of 18 dB. The isolator is available in a module where the input and output ports are WR-12 waveguides with UG387/U flanges.
